DOOR HANGING AND SECURNG MEANS.

Application 'led March 25, 192.1. Serial 110.455,391.

To all whom t may concern.'

' Be it' known that I, JOHN H. STEWART, a citizen of Canada, and aresident of Rutherford, in the county of Bergen and State of NewJersey,.have invented a new and'Improved DoorH'anging and SecuringMeans, of which the following is a description.

My invention relates to sliding doors for freight cars, and moreparticularlyl the inivention lrelates to -a freight car doorl adapted tohave lateral movement to or from the doorway in addition to its slidingmovement, whereby to effect a tight fitting of the door in the doorway.f The invention has for its general object to provide suspension meansfor the door, whereby. the door ma with facility4 be readquickly andtightly closed, as well as .to provide means coordi nated with thesuspension means for fasteningthe door in the closed position.

eference is to be had to the accompanying drawings forming a part ofthisfspeci-v vfication, it being understood that the drawings are merelyillustrative of one example of the invention.

Figure 1 is an elevation of a portion of a i freight car and the doorthereof embodying my invention;

Figure 2-.is a -fragmentary longitudinal vertical section of a freightcar giving an inside view of the door and its appurtenances;

`Figure 3 is a horizontal section on the indicated line 3 3, Figure 1;.

Figure 4 is a view inthe plane indicated by the dot-anddash line 4 4,lFigurel, but

, showing the door in the open position as in Figure 2;

'Figure 5 shows the upper portion of the door in side elevation bydotted lines and thecar roof in vertical section by full lines; Figure 6is a transverse vertical section on the line* 6 6, Figure 3;

Figure 7 is a transverse vertical section on Figure 8 is an'enlargeddetail inhorizontal section given to show the lower stop 4bracket andbearing, as hereinafter referred to; f

Figure 9 is an enlarged detail on the line 9 9, Figure 2.

In the illustrated example of my invention thel letter A indicates thedoor; B, the door f frame; and C, portions of the car body.V The4numeral 10 indicates a suspension bar of orifice. y

suitable flat material which is pivoted at its l upper end to thedoorAv-at the approximate vertical median line thereof at the inner side-of saiddoor as at 11. The lower end of the suspension bar 10 ispivotally connected' as at 12 to a suspension bar 13 preferablybetweenthe ends of said bar for reason that will appear. Above the'pivot12 the suspension 4bar 13 is pivotally secured as by a pin '14.

to'bracket 15' at one side of the doorway on the face of the adjacent`vertical member or jamb. Thus, the bars 10, 13 may have movement on thepivots 11, '12 and 14 with the sliding ofthesdoor A.- 'The'bracket 15 isadapted to swing in a plane transverse to the planev of the' doorway byreason of being pivotally secured at its lower, end as as 16,

the pivot pin 14 being at the upper end of said bracket. swingablebracket 15 has a slot and pin con-l nction with the door frame, therebeing a transverse slot 17 in said bracket, and a pin l18. passingthrough said 'slot into the door frame and limiting' the swingingmovement of the bracket.` l

The bar- 10 in coaction with the -bar 13 0r'- with that portion of' thebar between the pivots 12 and 14, constitutes a suspension means for thedoor but I provide the bar 13 lto extend below the pivot 12 asubstantial Advantageously, also, thev distance to assist as one meansto prevent ythe v turning of the door in its own plane with the pivotl11 as a center, the lower end of thebar 13 having' a transverse pin 1 9having lmovement'in a vertical slot 2O in a gulde bracket 21'suitab1ysecured to the inner face of the doorjA as bv rivets 22, the broad head19El of the pin 19 'being housed within saidy bracket' 21 for preventingdisplacement of the pin. Gruide'means for the door is proslidingmovement of the door to or from the closed position. The weight of thedoorV is sustained by the bars-10, 13 not by brackets 23, 24 and theguide rail v 25. The rail 25 1s U-shaped in cross section,beingupturnedat lvided `also in the form of brackets 23, 24

-with 'the brackets- 23, 24 fory the complete i the inner sid@ clearlyshown 1n lrigures.`

6 and 7 and the upper ends of the brackets 23, 24 are turned outwardlyand downwardly giving them a hook format the up- Y per ends, the reverseof said U-shaped rail 25. The bracket 23 engages the rail 25 at alltimes both in the closed and open positions of' the door but the bracket24 is adapted when the door is at the doorway B tomove toward or fromthe doorway and into and out of engagement with the guide rail 25. Forthe movement of the bracket 24 into and out of engagement with the guiderail 25, the vlatter is formed inits up- `turned portion with acut-out26 aording clearance for the hooked end of bracket 24 to move laterallyrelatively to said guide rail with the movement of the door transverselyto the plane ofthe doorway. stop bracket 27 is provided on the body C atthe bottom adjacent to thatside of the door frame having the swingingbracket 15.

The door A, it will be observed, when in the closed position, lies in aplane outside of \the pivotal connection 14 between the suspensionelement 13 and the car body and thereby .the door has a tendenc to moveoutwardly from the opening under its own weight.. I provide means foreffecting the tight closure of the door A., and for fastening the doorin the closed position of Figure 3, said means consisting of a verticalrod 30 adapted to turn at its upper. and lower ends respectively inbearings 28, 29 on the car body to permit said rod to turn through 180.-On the rod 30 are lateral fastener arms 31, 32 .near the topand' bottomof the rod respectively the lower arm 32 being longer and constituting ahasp to permit the( arm to pass over a staple 33 on the door A' adaptedto receive a padlock. The arrangement of the lock rod with its arms issuch that if the door A in the closing movement thereof arrives adjacentto the doorway, but not quite in register therewith,

. the arm 32 is grasped to turn the rod 30 on its axis and cause `saidarm 32to be pressed against the door at the adjacent edge whereby thedoor will be forced to move both in its own plane and laterally inwardto the plane of the'doorway. The rod 3Qiis halfround and when -inposition with the arms 31, 32, away from the door, said rod isaccommodated in a concave vertical recess c in the carfsiding adjacentto the door frame B and as indicated in Figures 3 and 4.

At the' opposite side of the doorway from thelocking rod 30 keeperplat'es34 are secured to the car to project beyond the door frame,whereby the adjacent edge of the door may be slid beneath said keeperswhen the door is moved to position at the doorway under pressure of thearm 32.

A keeper 35 is provided on the side of the car body to engage that edgeofthe door farthest from the door opening when the about the pivot 14,by the track 25 and its supporting means, andsince at the bottom thereis a Aslot and pin connection between the door and the element13"byreason of the pivot 19 sliding in the guide slot 20, which isdirectly in alinement with the pivot point 11, the door is constrainedto move in a straight line without rising orfalling moven l ment.

It will be observed also that by the suspension means described I amenabledto dispose the suspension means at the 1ns1de of the door,notwithstanding the limitations l as to space determined by theunalterable positions of the frame beams of the car body above and belowthe door opening, the result bein attained by reason of the suspension eements being arranged toA impart direct rectilineal movement to the doorand by the fact that the pivotal connection at 14 is at the door openingbelow that car beam which is positioned above thedoor. Therefore, thesuspension means is accommodated between the upper and lowerlongitudinal frame beams and therefore maybe mounted close to the doorin a plane para-llel with the door.

I would state in conclusion that while the illustrated examplesconstitute practical embodiments of my invention, I do not limit myselfstrictly to the mechanical details herein illustrated, since manifestlythe same can be considerably varied without (de-V parture` from thespirit of the invention as defined in the appended claims.

Having thus described my invention, I claim:
